Hertel 1000180 Mtgn Negative Rake Indexable Turning Toolholder

Product Description

The HERTEL 1000180 is a right-hand MTGN-style indexable turning toolholder designed for negative-rake external turning operations on CNC and manual lathes. Built from steel, it features a 1 inch x 1 inch square shank and measures 6 inches in overall length. The holder uses a clamp-and-screw insert retention method and accepts TN..43. style inserts with a 0.5 inch inscribed circle. The negative 5-degree rake angle suits heavy interrupted cuts and hard materials where edge strength is a priority. Installed by machinists and tool-room technicians, this holder fits into standard boring bars and tool blocks commonly found in production turning centers.

This toolholder is suited for general-purpose external turning in both job-shop and production environments. The MTGN style is commonly used for straight turning, facing, and light profiling passes. The 1 inch x 1 inch shank fits standard tool blocks and quick-change toolpost holders sized for that shank cross-section. The 1.25 inch back-of-bar to cutting edge dimension positions the insert for consistent depth-of-cut control. This is a single-use-per-setup holder with no coolant-through capability, making it straightforward to set up without internal coolant plumbing.

Installation Notes

Inspect the clamp, screw, and insert seating pocket for chips or damage each time the insert is indexed.
